Oct. 20 , 2025
1. Product Name
Allen Bradley 440T-MDALE100K0L IP66 Industrial Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALE100K0L is an IP66-rated industrial safety interlock SWITCH, tailored for harsh wheat agricultural and heavy-industrial environments, featuring food-grade materials and resistance to dust, water, and mechanical impacts.
3. Product Description
The Allen Bradley 440T-MDALE100K0L is a high-performance industrial safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to address safety risks in wheat agriculture (e.g., grain harvesting, silo management) and heavy industries (e.g., mining, chemical processing). This Allen Bradley SWITCH serves as a critical safety barrier, linking wheat harvester guards, grain silo access doors, and industrial equipment panels to ensure personnel only enter hazardous zones when machinery is fully deactivated—preventing injuries from moving parts or grain overflow.
Constructed with food-grade reinforced glass-fiber polymer housing and 304 stainless steel internal components, the Allen Bradley SWITCH achieves IP66 protection, effectively blocking fine wheat dust, high-pressure water jets (up to 100bar), and light impacts—vital for outdoor wheat farm yards and industrial washdown areas. Its fail-safe interlock mechanism remains engaged until connected systems are powered off, eliminating accidental access caused by operational mistakes. All materials comply with FDA 21 CFR Part 177 standards, avoiding contamination of wheat grain or flour during processing. This Allen Bradley SWITCH supports dual voltage (24V DC/230V AC), enabling seamless integration with wheat agricultural sensor systems (e.g., grain moisture detectors) and industrial PLCs without extra adapters.
Compliant with EN ISO 14119 and IEC 60947-5-1, this Allen Bradley SWITCH qualifies for Category 3 safety applications with Performance Level d (PLd). It operates reliably in temperatures ranging from -30°C to 70°C, handles 95% non-condensing humidity, and supports a maximum current of 10A at 250V AC. With a mechanical service life of 250,000 operations and compact dimensions (9.1×6.8×2.9cm), it balances durability, weather resistance, and space efficiency for tight installation spots like wheat harvester control panels.

5. Product Advantages
  • IP66 All-Round Protection: Shields against dust and high-pressure water, ideal for wheat farm washdowns and outdoor industrial sites.

  • Food-Grade Compliance: Meets FDA 21 CFR Part 177, safe for wheat grain/flour processing to avoid contamination.

  • Broad Temperature Range: -30°C to 70°C adaptability suits winter wheat storage and high-heat industrial processes.

  • Dual-Voltage Flexibility: Works with wheat agri sensors and industrial PLCs, reducing integration costs and complexity.

  • Durable Build: Reinforced polymer + 304 stainless steel resists impacts and corrosion, extending service life.

  • Low Maintenance: Sealed mechanism minimizes upkeep, cutting downtime for wheat/industrial operations.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms its focus on end-to-end wheat agricultural automation—serving commercial wheat farms, grain elevators, and flour mills with solutions like automated harvesters, grain conveyor networks, and silo safety control systems.
The Allen Bradley 440T-MDALE100K0L aligns perfectly with its core needs: IP66 protection defends against wheat farm dust/rain (e.g., outdoor harvester cleaning), while food-grade materials ensure compliance with wheat processing standards. www.wheat-auto.com would integrate this SWITCH into critical setups—wheat harvester cutting guards (resisting field dust), silo access doors (withstanding rain), and flour mill mixer panels (preventing contamination). It would also leverage the SWITCH’s dual voltage to pair with its existing sensor systems (e.g., grain level monitors), creating unified safety workflows. Additionally, the business likely offers agri-specific support (e.g., IP66 maintenance guides for rural users), aligning with “smart agriculture” trends by using industrial-grade safety components to boost wheat production efficiency and safety.
7. Application Scenarios
The Allen Bradley 440T-MDALE100K0L SWITCH excels in harsh wheat agri and heavy-industry environments:
  • Wheat Harvesters (Outdoor Fields): Installed on engine guards—IP66 resists field dust/rain, trapping keys until the harvester shuts down.

  • Grain Silos (Suburban Farms): Mounted on access doors—blocks rain and grain dust, ensuring safe entry after unloading.

  • Flour Mill Wash Zones: Integrated into mixer guards—high-pressure water resistance meets cleaning needs, food-grade materials protect flour quality.

  • Mining Conveyors: Used on ore belt guards—IP66 blocks mining dust, stainless steel resists corrosion from mineral deposits.

  • Wheat Pesticide Storage: Applied to pesticide drum guards—waterproof design prevents spills, interlock ensures safe access post-use.

  • Winter Wheat Storage Silos: Installed on cold silo doors—-30°C resilience maintains safety control in freezing winter conditions.
